Duplicate songs appearing in My Music

Songs are duplicating in My Music when I've added an album for offline playback and then a playlist that includes a song from an album I've already added. I am selecting to make available offline twice (once on the album and then once on the playlist). I was hoping Apple would make it smart enough to know I've downloaded the song once already and not download it again.

I just created a "test" playlist on my phone and added a song from an album I had already downloaded for offline use. When I then made that new playlist available for offline use, I did not get a duplicate of the song in "My Music." I thought it might be different if it was an Apple Music album/song versus one I already owned and the service either matched or uploaded to make it available in my library, so I downloaded an entire album added from Apple Music and then added a song from the album to the test playlist. Since I had already made the playlist available for offline use, it downloaded the song automatically (I always wondered if it would do this and I'm glad to see it does). I double checked to make sure it was in fact downloaded and then looked in my library and did not have a duplicate.

Not sure if this helps, except for us to know that it *should* not work the way it's working for you.

For me this issue is occurring when the playlist is coming from an Apple Music playlist. I am able to delete the duplicate track. It's more of an annoyance than anything.

At first I thought the issue may have been from making an album available offline I owned and then adding an Apple Music playlist. I have still seen it occur with an Apple Music album and Apple Music playlist.
